Abstract

An X-ray-sensitive camera comprising a first X-ray-sensitive image detector for the creation of a first tomographic image with a first depth of focus profile, a second X-ray-sensitive image detector for the creation of a second tomographic image with a second depth of focus profile, and an adjustment device for moving as desired the first image detector or the second image detector into proper alignment with an X-ray emitter for the creation of a respective X-ray image, the second depth of focus profile being smaller than the first depth of focus profile, the image-sensitive active surface of the second image detector being at least twice as large as an image-sensitive active surface of the first image detector in a first dimension, and/or the second image detector is not more than half as large as the first image detector in a second dimension, the first and second image detectors being disposed in a common casing with the camera, and the second image detector is disposed alongside the first image detector.
